What You’ll Need:

The slow cooker chicken fajita ingredients are so simple.

  • Tomatoes: You can use chopped tomatoes of any sort and keep the skin on.
  • Garlic: The freshly added garlic adds flavor to the fajita recipe.

How to Make Crockpot Chicken Fajitas:

This recipe comes together so quickly, and you can have it in the crockpot in just 10 minutes of prep time. We used our 6-quart slow cooker.

  • Cut meat: Slice the chicken into strips.
  • Cut vegetables: Slice the onion and julienne cut carrots.
  • Make seasoning: In a bowl combine the spices for the seasoning, combine the salt black pepper, garlic powder, onion powder, ground paprika, Italian seasoning, and cayenne pepper.
  • Cook: Add chicken, vegetables, tomatoes, garlic, and seasoning to your slow cooker until tender. Gently toss before serving.
  • Serve and Enjoy!
COOK TIME: The cooking time in the slow cooker will vary slightly depending on the side of your crockpot and how thick you cut your pieces.
-Cook on high for 2 – 3 hours. Cook on low for 4 hours.

Variations & Substitutions:

  • Salsa- instead of tomatoes, add your favorite salsa.
  • Different protein- you can use different meat like beef or shrimp. If you use a different meat the cooking time will slightly vary.
  • Traditional- traditional fajitas don’t have carrots and mushrooms. So, if you are looking for a classic chicken fajita recipe, leave out the carrots and mushrooms.

Serving Suggestions:

Serve the chicken fajitas with your favorite Mexican side. Here are some great ideas:

  • In flour tortillas like tacos, we like to toast them
  • Freshly squeezed lime juice
  • Chopped fresh cilantro adds so much flavor
  • With baked rice
  • The Classic Pico de Gallo
  • Your favorite shredded cheese will work
  • Any sour cream will work
  • A side of black beans or your favorite beans
  • Our homemade guacamole or store-bought
Serve Buffet Style: These fajitas are great to serve buffet style with toppings in bowls allowing everyone to build their own fajita dish or bowl.

Frequently Asked Questions:

Can I use taco seasoning?

Though we love the little kick from the Cajun seasoning, you may definitely just Homemade Taco Seasoning or store-bought.

Can I freeze the chicken fajitas mixture?

Yes, definitely. Once cooled, add to a freezer bag and flatten out the mixture. Freeze for up to 2 to 3 months.

What tortillas as best?

We prefer flour tortillas with the fajitas but corn tortillas may also be used. We love toasting the tortillas for crispiness and serving them warm.

How to store leftovers?

Keep the leftover fajita mixture in an airtight container in the fridge up to 3 days.
